PPARA and diabetes mellitus: The PPARα 162Val allele was nearly associated with higher HDL levels at univariate (46.1 ± 14 vs. 43 ± 10 mg/dl, p = 0.051), but not at multivariate analysis, and patients positive for this allele had a trend for a higher prevalence of diabetes/IFG compared to those without (25% vs. 16%; p = 0.06).
